摘要
随着需求的不断提高,变流器控制平台中,越来越多的使用到了异构多核芯片处理架构,复杂的数据链路不可避免的给数据传输带来难度。本文根据其控制芯片多、数据交互量大、实时性要求高、数据链路长的特点,提出了一套稳定可靠的高速数据传输方法,解决异构多核平台跨时钟域数据传输过程中的丢包和重包问题。
With the continuous improvement of demand,more and more heterogeneous multi-core chip processing architecture is used in converter control platform.The complex data link inevitably brings difficulties to data transmission.In this paper,according to the characteristics of multiple control chips,large amount of data interaction,high real-time requirements and long data link,a set of stable and reliable high-speed data transmission method is proposed to solve the problem of packet loss and packet duplication in the cross clock domain data transmission of heterogeneous multi-core platforms.
